Frame Generator Frame Length Register

Device Address: 0x1F; Register Address: 0x8025, Reset: 0x006B, Name: FG_FRM_LEN

This register specifies the data field frame length in bytes. In addition to the data field, six bytes are added for the source address, six bytes

for the destination address, two bytes for the length field, and four bytes for the frame check sequence (FCS). The total length is the data field

length plus 18.
